ENCLOSURE DETAILS
1. Parameters listed are for conventional applications only, for further help
please call Sound Pros Tech Support.
2. At least 0.75” MDF (Medium Density Fiberboard) is recommended for any
enclosure.
3. Recommended enclosures are NET box volumes, speaker and port
displacement are calculated into the volume of the enclosure, you will need
to add these volumes to calculate GROSS volume for the enclosure.
NOTES
* Due to the high power capabilities and long excursion of the HCCA woofers,
the Thiele/Small Parameters were calculated and measured using Klippel
analyzer system.
** Energy Bandwidth Product (EBP) is determined by the following formula Fs/
Qes=EBP. EBP values of 50 and lower suggest a sealed enclosure is best, 50 to
90 means the subwoofer versatile and 90 and above mean vented Enclosure is
recommended.
*** Subsonic lter should always be used and adjusted specically for vented
box designs.
ENCLOSURE DESIGN
This section gives the basic description for a sealed enclosure. Orion HCCA
woofers are designed for sealed enclosures and vented enclosures. Sealed
enclosures are generally considered the most versatile for all music types and
are the easiest to build. They will also give high power handling with a wider
range of frequencies. The enclosure must be absolutely air tight. Use a high
quality wood glue for all seams of the enclosure. The enclosure should also
be screwed together. The enclosure should be no less than 3/4” on sides. The
bafe board (woofer mounting plate) should be no less than 1”. If the woofer
mounting is to be recessed then a minimum of two 3/4” plates together
should be used. As MDF is a porous material it is best to also seal the inside of
the enclosure.
NOTE: The woofer must face up or down only, specially in sealed enclosures.
NOTE: Refer to the website www.orioncaraudio.com for updated enclosure
data for your woofer application.
